VENTILATOR FOR WATER-CLOSETS.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed January 19, 1917. Serial No. 143,217.

To all whom it may concern:

Be it known that I, ERNST F. KLEMME, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Ventilators vfor Water-Closets, of which the following is a. description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to ventilators for water closets and has for its object to establish a ventilating connection between the closet bowl and a vent pipe by way of the ordinary flushing pipe connection, said ventilating connection being valve controlled and the valve being so arranged that it will be automatically opened by pressure on the closet seatand automatically closed by the flow of water through the flushing pipe.

With the above and other objects in view, the invention consists in the ventilator for water closets as herein claimed and all equivalents.

Referring to the accompanying drawings, in which like reference characters indicate the same parts in different views:

Figure 1 is a side view of a water closet provided with a ventilator constructed in accordance with this invention;

Fig. 2 is a plan view thereof with the seat cover removed leaving its spring and push lug in position;

Fig. 3 is a sectional view of the valve in its open position and showing in dotted lines the closed position to which it is moved by the flow of water through the flushing pipe;

Fig. 4: is a similar view showing the normal closed position of the valve;

Fig. 5 is a vertical sectional view through the valve casing on the axis thereof;

Fig. 6 is a perspective view of the valve member; and,

Fig. 7 is a perspective view of the valve push rod and its associated parts.

In these drawings 10 indicates a cylindrical valve casing having integral tubular members 11 and 12 at the top and bottom thereof, the former for connection with the flushing tank 13 and the latter for connection with the closet bowl 14 and both together constituting an elbow-like flushing pipe connection through which water is discharged into the bowl in the usual manner. The casing 10 has integrally formed on it a third tubular member 15 which spreads out in a fan-like form to unite with the casing from end to end thereof so that its communicating opening is a long narrow slot. This tubular member 15 constitutes a vent pipe connection coupled with the vent pipe 16 with which the various traps of the plumbing system may be connected.

l/Vithin the casing 10 and fitting close to the walls thereof is a valve member 17 with. trunnions 18 at its end fitting in suitable bearings in end caps 19 which are preferably threaded on the ends of the casing. The valve member consists of a light casting forming a skeleton cylinder-like body with four co-axial disks 20 and 21 spaced apart so that the two middle disks 20 are at opposite sides of the water pipe connection 11 and the two end disks 21 are at opposite ends of the elongated port of the vent pipe connection 15. Extending across the edges of the disks from one end of the valve member to the other are a pair of shutters 22 and 23 spaced apart so thatthe slot between them may register with the vent port in one position of the valve though either may close said port in other positions. At the outer edge of shutter 22 and connecting the inner disks 20 is a radial water blade 24: which stands in an incline in the path of the flow of water through the flush connection so as to be moved thereby to the position shown in dotted lines in Fig. 3. W'eights 25 between the disks 20 and 21 at each end of the valve member are opposite the shutters and tend to turn the valve member to its normal position shown in Fig. 4 with the shutter 23 closing the vent opening. The valve member as described is preferably of an integral casting though it may be otherwise and the disks may be cutaway as shown to reduce the weight. Suitable stops 26 on the casing limit the movements of the valve member by engagement therewith.

On the projecting trunnion 18 of the valve member, outside the casing, is a collar 27 carrying an upstanding lug by means of which the valve is turned. A push rod 28 supported by guide strip 29 and washer 30 abuts one end against'the lug of collar 27 and its other end is engaged by a lug 31 secured to the bottom of the closet seat 32. The guide strip 29 is fastened on the valve casing and the washer 30 is placed under one of the hinge posts of the closet seat as seen in Fig. 2.

The closet seat is normally held in a slightly raised position by means of a spring 33 secured thereto and bearing on the edge of the closet bowl, but the spring yields to pressure on the closet seat to permit the latter to swing downwardly and in so doing push the rod 28 to turn the valve.

The normal position of the valve is such that the shutter 23 closes the vent opening as in Fig. 4, and from this position it is I the water acting upon the blade 24 to press it downwardly and so turn the valve farther to the position in dotted lines in Fig. 3 where shutter 22 closes the vent opening. The flow of water is therefore prevented from drawing air and gas from the vent pipe back into the room. When the flow of water ceases the weights return the valve to the open position if the seat is still depressed or to its normal closed position if the seat is released. I

By means of this invention a strong eflicient ventilation of the bowl is produced automatically when in use and is discontinued automatically when not in use or when the water flows. 7

Obviously the device is not confined to the specific details shown, for various changes may be made therein without departing from the invention. Any other form of operating means for the valve may be substituted, but that shown is at present.

preferred.

What I claim as new and desire to secure by Letters Patent is:

1. A ventilator for water closets, comprising a vent controlling valve in the flushing pipe closed by a flow of water through the flushing pipe and other means for opening and closing the valve.

2. A ventilator for water closets, comprising a vent controlling valve in thefiushing pipe closed by the flow of water through the flushing pipe and means operated by the closet seat for automatically opening the valve.

3. A ventilator for water closets, comprising a vent connection with the flushing pipe, a valve for controlling same, means influenced by a flow of water through the flushing pipe for closing the valve, and other means for opening and closing the valve.

t. A ventilator for water closets, comprising a casing having a passageway therethrough forming a flushing pipe connection, a vent pipe connecting with the casing, a rotary valve within the casing normally closing the vent opening, means for opening and closing the valve, and means for closing the valve while water is passlng through the flushing pipe connection.

.5. A ventilator for water closets, COIl1pIlB- ing a casing having a passageway therethrough forming a flushing pipe conneetion, a vent pipe connecting with the casing, a rotary valve within the casing having a pair of shutters spaced apart, means for holding the valve in a normal position with one shutter closing the vent, means for turning the valve to open the vent between the shutters, and means on the valve influenced by a flow of water through the flushing pipe for turning the valve to close the vent with the other shutter.

6. A ventilator for water closets, comprising a cylindrical casing having tubular projections forming a flushing pipe connection and a flaring vent pipe connection, a rotary valve member within the casing with a weight on one side and spaced shutters on the opposite side for communication with the vent, a water blade on the valve member in the path of flow or" water through the flushing pipe connection, a suitably guided push rod engaged therewith, a spring raised closet seat, and a lug on the closet seat engaging the push rod for operating the valve.

7. A ventilator for water closets, comprising a vent controlling valve in the flushing pipe closed by a flow of water through the flushing pipe, and other means for auto matically opening and closing the valve.

8. A ventilator for water closets, comprising a normally closed vent controlling valve in the flushing pipe closed by the flow of water through the flushing pipe, and means operated by the closet seat for automatically opening the valve.

In'testimony whereof, I aflix my signa ture, in presence of two witnesses.
